After first meeting when they appeared together on MTV's "16 & Pregnant," Chelsea and Kail established a close friendship and as time, and "Teen Mom 2," has gone on, it's only gotten stronger. But unfortunately, with Chelsea in South Dakota and Kail in Delaware, the pair don't see each other as much as they'd like to.
Although they unite about twice a year to film the reunion and after shows, Chelsea and Kail don't see much more of each other -- unless they plan trips, which Kail currently has in the works.
As for the other two girls, Leah Calvert and Jenelle Evans, they are a bit more distance -- especially when it comes to Jenelle. Because of Jenelle's "Teen Mom" website and reporting on Kail, Chelsea, and Leah, she's what one might refer to as the black sheep of the group. She's even known to publicly feud with cast members and just last month told Kail to "leave her the f**k alone," following an argument.
